The calories in GU's Roctane drink come from its proprietary blend of maltodextrin and fructose
(complex and simple carbohydrates). Complex Carbohydrates are long chains of sugars.
Humans store them as glycogen in the muscles and liver. In the Roctane drink, maltodextrin is
an easily digestible, complex carbohydrate derived from corn. Maltodextrin (a glucose polymer)
provides a large amount of energy without being too sweet.
Simple Carbohydrates in the Roctane drink come from fructose, a fruit sugar, which converts to
glucose more slowly. Fructose is mainly metabolized to glucose in the liver.
Over the years, this two part carbohydrate system has been shown to maintain glucose levels as
a preloading food before intense short competitions or for many hours over endurance events.
The combination of maltodextrin and fructose will also lead to greater muscle glycogen
resynthesis after exercise (better recovery).
Consumption of carbohydrates during endurance events can delay fatigue and improve athletic
performance by preventing hypoglycemia and maintaining high rates of carbohydrate oxidation
during the final stages of exercise, when glycogen stores are low. Quite simply, carbohydrates
are the body's primary energy source. Unfortunately however, carbohydrates are not stored in
inexhaustible amounts. A 150?pound man has about 1500?1800 calories of carbohydrate in the
liver, blood and muscles. The amount of glycogen that a person has, ultimately will determine
how long they can maintain exercise. When glycogen levels are depleted the ability to exercise
decreases. Inadequate amounts of carbohydrate can force the body to begin to use a less
efficient source of fuel for energy, protein or fat. By consuming adequate levels of
carbohydrates, other energy sources like protein and fat do not have to be sacrificed as fuel and
consequently higher intensity exercise can be prolonged. Protein can then be used as a
substrate for tissue growth and repair. GU's Roctane drink has slightly more than double the
number of carbohydrate calories when compared to standard Electrolyte Brew yet its
formulation is optimized for efficient absorption.
Amino Acid Complex:
Protein is stored in the body as muscle. When the body uses protein for fuel, it will either, use
amino acids in the bloodstream from previously consumed food (Roctane Drink) or breakdown
Each protein is made up of various combinations of amino acids. Our dietary protein
requirement is to fulfill the need for amino acids. These molecules (20 of them) make up all of
the proteins in our diet. Nine of these are essential (this number can vary depending on age,
etc.), which means that our body cannot synthesize them and are therefore are required in our
diet on a daily basis. All amino acids are broken down in the liver except for 3 of the essential
amino acids: leucine, valine and isoleucine, the branched?chain amino acids (BCAAs), which are
taken up by the muscle. Muscle protein is constantly being made and broken down. The
recommended dietary intake for protein in the normal adult is 1g/kg body weight daily, while
endurance athletes have greater daily needs for protein intake of 1.2?1.8g/kg/ body weight to
maintain protein balance. This level of protein intake for strength and endurance athletes is
about 150?200% above RDA for the normal adult.
Type of amino acids in Roctane Drink
Roctane Drink contains the Branched?chain amino acids (BCAAs): leucine, valine and isoleucine.
Roctane Drink also contains Histidine, an essential amino acid that acts as a buffer to prevent
the accumulation of lactic acid in the muscle during exercise.
ROLE of BCAAs in Roctane Drink
Consumption of BCAAs plays an important role in athletic performance and recovery from
BCAAs as Fuel
BCAAs act as a fuel when converted to glucose during exercise in addition to carbohydrate.
Studies have shown during exercise, BCAAs requirement is increased; especially leucine. BCAAs
can contribute up to 10% of a muscle’'s energy. Exercise leads to significant drops in blood levels
of leucine following exercise: aerobic (to 33%), anaerobic lactic (to 8%) and strength (30%).
Branched chain amino acid intake (about 15kcals/hour ? equivalent of 50kcals/hour of regular
protein powder) has shown to have a positive effect on athletic performance when taken with
absorbable amounts of carbohydrates.
BCAA to reduce muscle damage and enhance recovery
To replace BCAA losses and maintain sufficient blood levels, the body will excessively break
down muscle. For this reason, suggestions have been made to increase the recommended
dietary intake of especially leucine by 3 fold. Research shows that 1.5g/day of BCAAs during
light training and 3g/day of BCAA during intense training can contribute to sparing muscle
glycogen stores in the liver and skeletal muscle during exercise. Consumption of these
suggested levels of amino acids can be met using GU's product line during training and racing.
